Abstract
A 2-month-old male infant presented with a persistent mild cough and a pink papule beneath the left eyelid. Imaging studies revealed diffuse lung opacities and a cystic shadow in the right middle lobe, with no evidence of bacterial or fungal infection. Skin biopsy demonstrated positive immunohistochemical staining for CD207/Langerin and CD1a, leading to a diagnosis of Langerhans-cell histiocytosis (LCH). The infant's pulmonary bullae resolved following chemotherapy, and the patient is under surveillance for recurrence. LCH, recognized for its inflammatory and malignant characteristics, often presents with multisystemic involvement, including pulmonary manifestations. Timely diagnosis and treatment are crucial for managing this rare disorder in infants.
期刊介绍：
Pediatric Pulmonology (PPUL) is the foremost global journal studying the respiratory system in disease and in health as it develops from intrauterine life though adolescence to adulthood. Combining explicit and informative analysis of clinical as well as basic scientific research, PPUL provides a look at the many facets of respiratory system disorders in infants and children, ranging from pathological anatomy, developmental issues, and pathophysiology to infectious disease, asthma, cystic fibrosis, and airborne toxins. Focused attention is given to the reporting of diagnostic and therapeutic methods for neonates, preschool children, and adolescents, the enduring effects of childhood respiratory diseases, and newly described infectious diseases.
PPUL concentrates on subject matters of crucial interest to specialists preparing for the Pediatric Subspecialty Examinations in the United States and other countries. With its attentive coverage and extensive clinical data, this journal is a principle source for pediatricians in practice and in training and a must have for all pediatric pulmonologists.
